Undertaking legal research involves navigating myriad primary and secondary sources to ensure accurate and comprehensive analysis of any multitude of legal topics. While primary sources like statutes, regulations, and case law are fundamental, secondary sources are equally valuable in providing context, interpretation, and analysis especially in an ever-changing landscape of emerging case law and policy. Among these secondary sources, client alerts have emerged as a significant resource to help keep legal professionals abreast of developments in the law and potential implications for their practices and clients. At times overnight, a particular legal issue can shift from primary authority to persuasive authority or could be overruled altogether. Failure to track these changes in real time can significantly impact a case and put the attorney at a considerable disadvantage—even risking the client's overall success in a case. This article explores the effective use of client alerts as secondary sources in legal research and highlights strategies to leverage them for enhanced insights and impact in current cases and as effective marketing tools.
